DETAILED DESCRIPTION OF CERTAIN EXEMPLARY EMBODIMENTS

Certain exemplary embodiments described herein comprise a spray devicethat is inserted directly into a fruit, vegetable, berry, or otherliquid source (again, for brevity, “fruit”). The spray devicefacilitates the spraying of juice directly from the fruit, thus avoidingthe limitations of the procedures described above.

FIGS. 1-4 illustrate a spray device 100, according to an exemplaryembodiment. As shown in FIG. 1, the spray device 100 may include a body110, an actuator 140, a pump 160, and an engagement member 120. The body110 may include a flared portion 111, configured to couple to theactuator 140, and a neck 112, configured to couple to the engagementmember 120. The body 110 may further include an inner surface 115 thatdefines a channel 116 and receives the pump 160 therebetween. Similarlystated, the pump 160 may be at least partially disposed within thechannel 116 defined by the inner surface 115 of the body 110.

The body 110 may be any appropriate shape, size, or configuration. Forexample, as shown in FIG. 1, the flared portion 111 of the body 110 mayinclude a first end (e.g., a top end) that defines a first diameter, anda second end (e.g., a bottom end) that defines a second diametersubstantially larger than the first diameter. In this manner, the flaredportion 111 may define an ergonomic shape such that a user's hand caneasily grasp the flared portion 111. Similarly stated, the flaredportion 111 can define a surface that prevents further insertion of thespray device 100 into a citrus fruit. That is, the flared portionprevents the product from being inserted too far into the fruit.

While the surface is shown in FIG. 1 as substantially smooth, the body110 can define any suitable surface. For example, in some embodiments,the flared portion 111 may include a grip with ridges and/or protrusionsconfigured to engage a user's hand or fingers.

The body 110 may be formed of any suitable material, such as, forexample, a plastic, thermoplastic, polymer, ceramic, metal, glass,and/or any combination thereof. Additionally, the flared portion 111 mayinclude any suitable surface treatment, such as, for example, a texturedsurface to increase the friction between a user's hand and the flaredportion 111.

The neck 112 may be configured to extend from the flared portion 111.While depicted in FIG. 1 as defining a smaller diameter than the flaredportion 111, the neck 112 may define any suitable size or shape. Forexample, in some embodiments, the neck 112 may be wider than the flaredportion 111. Alternatively, in other embodiments, the neck 112 may haveother cross-sections including, for example, oval, square, rectangular,etc.

Referring to FIG. 2, an actuator 140 may be configured to be operativecoupled to the body 110. More specifically, actuator 140 may include anouter surface 141 configured to be inserted into the channel 116 definedby the inner surface 115 of the body 110. Additionally, an inner surface145 of the actuator 140 may include an annular protrusion 146 thatextends from a top portion of the inner surface 115 (see FIG. 3). Theannular protrusion 146 may be configured to receive a portion of thepump 160. In this manner, the actuator 140 may be coupled to the pump160 and either or both may be disposed within the body 110.

The outer surface 141 of the actuator 140 may include an engagementportion 142. The engagement portion 142 may define an ergonomic shapeconfigured to receive a user's finger. In this manner, the user candepress the actuator 140 to actuate the spray device 100.

Additionally, the actuator 140 may include an outlet portion 143configured to receive a nozzle 150. The nozzle 150 may be any suitablenozzle configured to spray a liquid. In some embodiments, the nozzle 150may be integrally formed with the actuator 140. Similarly stated, insome embodiments, the outlet portion 143 of the actuator 140 may definean orifice configured to deliver a spray of a fluid.

As described above, the pump 160 may be at least partially disposedwithin the body 110 of the spray device 100. The pump 160 can be coupledto the body 110 in any suitable manner. For example, the inner surface115 of the body 110 may define an upper seat 117 configured to engage aportion of the pump 160. In some embodiments, the pump 160 may define afriction fit with the inner surface 115 of the body 110. In otherembodiments, the pump 160 and the body 110 may define a threadedcoupling. The pump 160 may be any suitable pump 160 configured todeliver a spray of a liquid. For example, in some embodiments, the pump160 may be a positive displacement pump.

In some embodiments, the pump 160 may be configured to deliver a fluidto an outlet and/or outlet portion in response to a negative pressuredifferential. For example, the pump 160 may be actuated such that airand/or fluid within a chamber is expelled. The expulsion of the airand/or fluid may cause a negative pressure to exist such that the pump160 draws a fluid through a suction tube into the chamber. In someembodiments, the pump 160 may include a valve assembly configured toopen and close in response to the actuator 140. For example, in someembodiments, the pump 160 may be configured such that when the actuator140 is depressed by a user the valve opens to deliver a fluid.

As described above, engagement member 120 may be configured to becoupled to the neck 112 of the body 110. More specifically, engagementmember 120 may include an extension 122 configured to be inserted intothe neck 112 of the body 110. The engagement member 120 may include anouter surface 121 that defines an annular slot 123 (see FIG. 4)configured to engage an annular protrusion 118 defined by the innersurface 115 of the body 110. Therefore, when the extension 122 of theengagement member 120 is inserted into the neck 112 of the body 110, theannular slot 123 may receive the annular protrusion 118. In this manner,engagement member 120 may be coupled to the body 110.

In some embodiments, an annular protrusion 118 may be formed of amaterial defining a high friction coefficient, such as, for example,polypropylene (PP). In other embodiments, an annular protrusion 118 maybe any suitable material and may be formed as an over mold (e.g., thebody 110 is formed of a given material and the annular protrusion 118 isformed of a second material, molded on top of the first material). Instill other embodiments, engagement member 120 may be coupled to theneck 112 of the body 110 using a threaded coupling. In such embodiments,engagement member 120 may be coupled to and decoupled from the body 110by twisting the engagement portion 120 relative to the body 110.Alternatively, engagement member 120 may be integrally formed with thebody 110 (e.g., engagement member 120 may be formed together with thebody 110).

Engagement member 120 may include an engagement portion 124 (see FIG.4). The engagement portion 124 may be configured to be inserted into thecitrus fruit. More specifically, the engagement portion 124 may includea serrated end surface 127 configured to cut the peel of a citrus fruitsuch that the engagement portion 124 may be inserted into the citrusfruit. Additionally, the engagement portion 124 may include a concavesurface 125 configured to receive a portion of the peel disposed withinthe engagement portion 124. Similarly stated, the concave surface 125may be configured to allow the serrated end surface 127 to extend beyondthe peel.

With the engagement portion 124 inserted into the citrus fruit, theactuator 140 may be actuated such that the pump 160 transfers a suctionforce to the citrus fruit. The engagement portion 124 may include a setof passages 126 configured to allow the juice within the fruit to enterthe engagement portion 124. More specifically, as juice is transferredthrough the passages 126, the juice can enter a channel 129 defined byan inner surface 128 of the engagement member 120 (see FIG. 3). Thechannel 129 may include a filter 130 configured to filter the juice ofpulp, seeds, and/or debris before entering a suction tube included inthe pump 160. The filter 130 may be any suitable filter such as, forexample, a mesh filter 130.

In such embodiments, the mesh filter 130 may define any suitable meshsize configured to allow for a given flow rate of juice through thefilter and may be made from metal, plastic, or any other suitablematerial. While depicted in FIGS. 3 and 4 as substantially thimbleshaped, the filter 130 may be any suitable shape.

For example, in some embodiments, the filter may be a flat disc, aconical filter, a frustoconical filter, a convex/concave filter, and/orany other suitable filter. In this manner, the juice contained in thecitrus fruit may be transferred to the pump 160 and delivered throughthe nozzle 150. In some embodiments, the mesh filter 130 may be removedto be cleaned. For example, a user may remove the engagement member 120from the body 110 by twisting the engagement portion 120 relative to thebody 110 to rinse the filter 130 of pulp, seeds, or other debris. Afterthe filter 130 is cleaned or replaced, it may be inserted back into theengagement portion 120 and re-coupled to the body 110. In someembodiments, the filter 130 may be integrally formed with the body 110and/or the engagement member 120.

In certain embodiments, instead of or in addition to using a separatefilter piece, functionality of a filter may be achieved using a set ofperforations in a bottom portion of a juice extractor component (see,for example, FIGS. 10, 11, and 13).

In certain exemplary embodiments, inserting of a bottom portion of thespray device, such as the engagement portion 124 (FIGS. 1-4), directlyinto a fruit (or vegetable, berry, etc.), may cause juice to flow fromthe fruit into a cavity, such as a channel 129 (FIG. 3), defined withinthe body of the spray device. Then, resulting from depressing of a pumpactivator (e.g., actuator 140, FIG. 3) of a pump (e.g., 160, FIG. 3), asuction force may cause the juice collected within the cavity to betransferred, via a pump tube, up towards the pump activator, andreleased via a nozzle (e.g., 150, FIG. 2) in small particles, such as amist.

Directing of the nozzle in a desired direction enables the user of thespray device to control the direction of the mist. The lower portion ofthe spray device may define one or more channels, such as passages 126(FIGS. 2-4), and/or a concave end with a plurality of openings tofacilitate and/or guide the flow of the fruit juice into the cavity uponinsertion of the spray device into the fruit. Although FIGS. 1-4 depictthe spay device including four channels, fewer or more channels may beformed within the lower portion of the spray device.

Another exemplary embodiment comprises a hand-held device for sprayingfruit juice directly from a fruit, vegetable, berry, or other liquidsource. The device comprises two parts: an aerosol spray pump componentand a juice extractor component (see FIG.

5). The aerosol spray pump component includes a pump, a pump activator,an aerosol port, a siphon tube, and a threaded collar. The juiceextractor component includes a threaded end, a hollow body part, a solidbody part with channels, and a serrated end.

The pump used in this exemplary embodiment may be cylindrical in shapeand made of hard plastic. The siphon tube may be made from a hollow,flexible plastic tube and extend from one end of the pump.

The interior surface of the threaded collar may be threaded like ascrew. One end of the threaded collar may be closed and attached to theexterior surface of the pump where the pump meets the pump activator,while the other end may be open and encompass the pump. The juiceextractor may be a tube shaped cylinder that is hollow on one half andsolid on the other half, having a diameter that is slightly less thanthat of the threaded collar, but more than that of the pump.

All parts of the juice extractor may be made from hard plastic, may becylindrical, and may be formed from the same piece of material. One endof the hollow body part may be threaded like a screw on the exteriorsurface, comprising the threaded end. The opposing end of the hollowbody part integrates with the remaining half of the juice extractor, thesolid body part. Two channels may be cut perpendicular to each otherthrough the entirety of the solid body part, resulting in four coaxialchannels spaced at right angles to each other.

The end of the solid body part opposite that integrated to the hollowbody part may be concave and serrated, forming the serrated end. Thethreaded collar of the aerosol spray pump may be joined to the threadedend of the juice extractor with a twisting motion, with the pump fittinginto the hollow body part and the siphon tube fitting and reachinghalf-way into the solid body part with channels (FIGS. 5 and 6).
